This came up in a very recent thread...
What happens with me is something I call "revving". I get into this feedback loop where I *know* I have a ton of things to do, I can't pick one, they all seem important, everyone wants something yesterday, and AAAAAAAAHHH!!
When that happens, I suggest tequila. You can mix it or shoot it, but either way it tends to slow my brain down just enough that I can get onto the next thing. The next thing might be a nap, of course. Depends on how much tequila is involved.
In the recent past I have found myself in the "endless loop" mode. Where I have 3+ tasks on hand (>2 for me) and all of them are time-critical (happening now), and also require attention (I feel they're important), my brain can sometimes find itself in "endless loop mode"- or as Shane called it, Revving.
An example- I am a full time Graduate Student/Researcher, but a part-time Staff-Technician at my University (dropping the last when the semester starts, thank God). On Friday, we had a visitor from Hans-Meitner in Berlin. His work was critically close to my work, and so I knew devoting attention to him was important. However, I also had tasks in the same building a few floors up for my Staff job. Of course a few things were happening at once, and I ended up with too many things on my plate- so I went a bit into Endless Loop mode- effectively wasting about 1/2 hour or more during critical time. I need to temper that with the fact it wasn't really "critical time"... as a Grad-student all time is to some extent your time... so it's not like it was "company time"... but I could easily see it being company time in the future.
What was the appropriate response to having 4 things to do at once? I think I know some of the answers to this, but I think a discussion about how you like to deal with Revving and plowing through the tasks before you when it happens would be a great thing.

I unfortunately can't reach for the Don Julio Reposado while at work... so another option would be be good.

[Although, I have found myself in endless loop mode and had the ability to have a quick drink (think very late night writing/working)- and it's done wonders. Quiets the brain a bit and allows it to get moving on something.]
I'm all ears!
